Please help as I have the situation of needing to measure the temperature of fluids in a pipe and display those temperatures in a way that is visible from 15 to 20 feet away.
I am just learning about arduino and its capabilities and want to try it out. I am building a display for a trade show and would like to show the temperature change across a plate fin heat exchanger. I would like to broadcast the temperatures to a large screen or segmented LED.
My initial instinct was to use a thermocouple. I am sure I can get the thermocouple into the flow while finding a way to get the wire out of the pipe without spilling the contents of the system. Being a rookie at this, I want to hear how those who are experienced with arduino would do it. I am also concerned about converting the information into a visual display.
Thanks in advance.
